Answer:

<em>Answer: D 12,16,20</em>

Step-by-step explanation:

<u>The Pythagora's Theorem</u>

On a right triangle with side lengths of a,b, and c, being c the hypotenuse, of the longest side, it follows that:

a^2+b^2=c^2

The set {a,b,c} is often called a Pythagorean Triple.

Testing every option:

A

5^2+8^2=10^2

25+64 = 100

89 = 100

Since equality is false, 5,8,10 are not the side lengths of a right triangle.

B

3^2+5^2=7^2

9+25 = 49

34 = 49

Since equality is false, 3,5,7 are not the side lengths of a right triangle.

C

6^2+11^2=13^2

36+121 = 169

157 = 169

Since equality is false, 6,11,13 are not the side lengths of a right triangle.

D

12^2+16^2=20^2

144+256 = 400

400 = 400

Since equality is true, 12,16,20 could be the side lengths of a right triangle.

Answer: D 12,16,20

Answer:

Choice D

Step-by-step explanation:

If you check each one plugging in your info into this you can get a^{2} +b^{2} =c^{2} that 12² + 16² will equal 400 which is the same as 20².

One serving of chad's cereal is 1 1/4 ounces. How many servins are in 15 1/3 ounces box?
IrinaK [193]

12

change the mixed numbers to improper fractions before dividing

1 \frac{1}{4} = \frac{5}{4} and 15 \frac{1}{3} = \frac{46}{3}

divide contents of box by a serving

\frac{46}{3} ÷ \frac{5}{4}

change ÷ to × and turn the second fraction upside down

= \frac{46}{3} × \frac{4}{5}

= \frac{184}{15} = 12.26666 = 12 complete servings

Divide £50 in the ratio of 1:4
NikAS [45]
Answer=10:40


Explanation:

Don’t know how to type the symbol in font of the 50 so I will substitute
£50=$50

So 1:4
Add it up
1+4=5

So 5 total units
$50=5
Divided by 5
$10=1 units

So 1:4=10:10 times 4=10:40
